5. 50 Cent
While it’s not exactly jarring to see rappers perform live over a backing vocal track, it is a rarity to witness an MC go all-out Britney Spears. But that’s what happened during 50 Cent’s showing on the 2007 BET Awards. The Get Rich or Die Tryin’ rhymer made a grand entrance during a performance of his single “Amusement Park” as he was lowered from the heavens onto the stage. But once the chorus faded out, Fiddy continued to mouth the track’s lyrics as his longtime DJ, Whoo Kidd, accidentally played the instrumental version. The multi-millionaire business pitchman was forced to wander around the stage before the song was eventually re-set. What up, gangsta?
